2007 Jeep Wrangler: check engine light

Filed May 30, 2025 · Electrical, Engine · CT

In 2022, I paid over $15,000 to an official Jeep dealership (Chrysler Dodge Jeep RAM City, Greenwich CT) to replace the engine in my Jeep Wrangler. Without clear disclosure or consent, they installed a non-OEM Jasper remanufactured engine. The invoice misleadingly stated “ALL PARTS ARE NEW UNLESS OTHERWISE INDICATED,” with no mention of Jasper or warranty terms. The vehicle began malfunctioning almost immediately, raising multiple serious safety concerns, confirmed by written service exchanges: •“The Jeep is stopping alone! Just crazy, brakes come on alone” — 🛑 Spontaneous brake engagement poses a serious crash risk. •“It also smells strong gas when turning the car on” — 🚨 Potential fuel leak or misfire, which is a fire hazard. •“The Jeep is malfunctioning,” “check engine light came back on,” “needs a PCM”, followed by: “I’m not sure this is a computer problem, but the motor you folks placed in the car.” — ⚠️ Suggests deeper integration issues between the engine and vehicle electronics. After only ~8,000 miles, the engine failed again. I spent thousands more with an independent mechanic, who found that several parts supposedly replaced in 2022 were already failing again (spark plugs, oil cooler, manifold gaskets, thermostat). This points to reused components, poor-quality parts, or improper installation. Stellantis refuses to assist, claiming their dealership is “independent,” despite operating under Stellantis branding and authorization. A Stellantis rep confirmed they would only file an internal complaint and left me to handle everything alone. This reflects mechanical negligence, brand-level accountability failures, and clear safety threats. I’m requesting the federal safety agency investigate: •Post-engine replacement safety hazards and quality of work and materials •Dangerous servicing practices at this authorized dealership (if not many or all of them) •Stellantis’ lack of oversight over branded repairs

Strong smell of gas in the garage after shutting jeep off for past 3-4 years. Fuel spit issue resolved with warranty 12/2013. Gas smell after shutting jeep off continued. 09/2014 dealership pulled code p0456, "vent tube at tank broken." paid to have dealership order and install a new tank only to find the "new tank has crack at rollover valve," had to order a second replacement fuel tank, installed with no problems noted. Heavy smell of residual fuel in the garage continued to persist to the point where we have to leave the garage open to vent the fumes for fear of ignition. Could not visually identify any fuel leak. All the while have had intermittent check engine lights coming off and on pointing to emissions and fuel system. Another trip to the dealership 07/2015, pulled code p0406, stated "couldn't find anything at this time." heavy gas smell continues to get worse. 07/2016 took jeep to mechanic, pulled codes p0456 and p0486, found the fuel tank vent tube was cracked again, needed a new fuel tank and egr valve. Back to the dealership. Tank is out of warranty, have to replace the 22 month old fuel tank again. The fuel system has had consistent problems from inception. The heavy gas odor and cracked fuel tanks pose a serious life safety and environmental concern. It is only a matter of time before a vehicle and/or a residence catches fire. The continuous exposure to gas vapors alone is serious concern due to the carcinogenic nature of fuel and its vapors. After researching this issue in various jeep forums online, this does not seem to be a singular event and is actually quite common. Many jeep enthusiasts are diy'ers and are modifying/jury rigging the vent tube themselves instead of paying for a replacement tank, which means there are a lot of jeeps causing heightened emissions and pose further safety concerns that are going unreported and that you are unaware of.

Purchased 2007 wrangler sahara new. Maintained vehicle as suggested by manufacturer. Noticed early on the 3.8 l v6 burned oil. Was told this was normal, so I added a quart of oil every 1,000 miles. At 51,000 miles noticed a loud knock. Immediately took the vehicle in for service and was told that the engine was blown. I had changed the oil at 50,000 miles but somehow lost all of the oil in 1,000 miles. Never had a check engine light or oil warning light, no oil showing on the ground. Dealer wanted $7,000 to install remanufactured long block. Would not call chrysler on my behalf even though they had been the one servicing the vehicle. Chrysler refused any assistance since out of warranty. Three different customer service representatives refused to allow me to speak with anyone above them as the decision (made in one hour) was final. They refused to give me an address or fax number so that I could submit my service records to show that I had maintained the vehicle. In fact, they indicated that not only was a quart of oil every 700-1,000 miles was perfectly normal, that is was also normal to check the oil level at least once a week when fueling the vehicle. A quick review on the internet shows thousands with this problem. 650 signatures are on one petition alone that show this is a problem that chrysler refuses to acknowledge.

Tl*the contact owns a 2007 jeep wrangler. The contact drove into a mud puddle and then across a grass field. Three days later, he took the vehicle to the car wash and the check engine light illuminated. He took the vehicle to the dealer and they found a failure at the brake purge tank, which ripped and caused the brake line to pull down. The dealer informed the manufacturer that the cause of the failure was due to reckless driving. Therefore, the manufacturer stated that the warranty does not cover aggressive driving, only defected parts. The contact feels that his vehicle was designed to be driven on rough terrain; therefore, the brake purge tank is defective. The current and failure mileages were 10,000.
